Input Impedance Sensitivity Analysis of Patch Antenna with Discrete Perturbations on Method-of-Moment Grids

Abstract

A new practical approach is proposed to the response sensitivity analysis of highfrequency structures modeled with the method of moments. The response sensitivities are calculated with the self-adjoint approach and discrete shape perturbations on the method of moments grids. The approach requires certain computational effort as a pre-process. This effort is due to building a global system matrix that covers all possible geometrical variations which may arise during design optimization. The technique is illustrated through the sensitivity analysis of the input impedance of a Yagi-Uda array and a printed patch antenna. The computed sensitivities are validated by comparing with the central finitedifference estimates at the response level.
